Abstract

A polarity independent, ultra-low input voltage step-up converter (200) comprising: an input source (205) having a variable polarity; a step-up transformer (T1) including a primary winding (210) and two secondary windings (215,220) coupled to the input source (205); a first depletion mode transistor (225) coupled at its first terminal to the input source (205) and at its second terminal to a reference point; and a second depletion mode transistor (240) coupled at its first terminal to the primary winding (210) and at its second terminal to the reference point. The input source (205) may include a Peltier cell. The first and second depletion mode transistors may be N-channel JFETs.
